According to some research, males have better spatial skills than do females; and according to other research, females have better reading skills than males. A student is interested in determining which sex performs better on a word-search puzzle (a puzzle in which the words are hidden vertically, horizontally, and diagonally within an array of letters) since this type of puzzle involves both spatial and reading skills. A sample of males and females volunteer to participate and are given 10 minutes to work on a 50-word puzzle. The number of words correctly recognized is recorded for each subject, and the resulting data are as follows:

Males Females
12 15
8 12
9 11
11 18
10 13
12 14
7 17

Conduct the appropriate analysis of these data and determine whether there are any significant differences.
